Description

Technical Field

[0001] The present application relates to the field of communication technology, and more specifically, to a communication method and a communication device for sensing. Background Art

[0002] In the process of the fifth generation mobile communication system (5G) evolving into 5G-Advanced (5G-A), communication and perception integration technology is considered to be one of the key technologies that can expand the business capabilities of mobile communication networks. This technology aims to integrate wireless communication and perception functions into the same system, and build the ability to detect and image targets by utilizing the various propagation characteristics of wireless signals, so that communication and perception capabilities can be integrated into one network to achieve harmonious coexistence and even mutual benefit.

[0003] In the perception scenario, multiple perception entities may be involved. These multiple perception entities can collect data within the coverage of their respective perception services, so as to collaborate to complete the perception service. Considering that the perception target may be mobile, when the perception target moves, it may move out of the perception service range of the current perception entity and enter an area that cannot be perceived, resulting in the inability to continuously perform the perception service.

[0004] Therefore, there is an urgent need for a communication method for sensing that can ensure the continuity of wireless sensing services when the sensing target moves. Summary of the invention

[0005] The present application provides a communication method and a communication device for perception, which can ensure the continuity of wireless perception services when the perception target moves.

[0006] In a first aspect, a communication method for perception is provided, which can be performed by a first perception entity or a first network device, or can be performed by a chip or circuit configured in the first perception entity or the first network device, or can be performed by a logic module or software that can implement all or part of the functions of the first perception entity or the first network device. This application is not limited to this.

[0007] The method includes: receiving first configuration information, the first configuration information including a first threshold, the first threshold is used to indicate the perception range of the first perception entity for a first perception service, the first threshold is determined based on the service requirements of the first perception service, and the first perception service is implemented based on the first perception entity's perception of a first perception target; determining another perception entity to execute the first perception service based on the first configuration information and the location information of the first perception target.

[0008] In the present application, the method can be applied to a first perception entity or a first network device.

[0009] Among them, the first perception entity is an access network device or terminal device with perception function, which is not limited in this application.

[0010] The first network device is a network entity having a perception data processing function, such as SDPF.

[0011] In a perception scenario, when the perception target moves within the maximum perception service range of the perception entity, the perception entity can determine valid perception data based on the perception signal. However, for the perception needs of different perception services, even if the perception target moves within the maximum perception service range, the continuity of the perception target's perception service may not be guaranteed, and the current perception service may be interrupted or have other failures. The present application proposes to determine another perception entity to perform the current perception service based on the perception range of the business needs of the perception service, wherein the stability of the service can be ensured when the perception target moves within the perception range based on the business needs of the perception service, and another perception entity can be determined based on the perception range to perform the current perception service, thereby ensuring the continuity of the perception service. In other words, the perception entity not only needs to be able to meet the maximum perception service range, but also needs to meet the perception range of the business needs of the current perception service. This ensures that the effective perception data of the perception service is continuously uploaded, meets the needs of the perception service, and improves the perception capability.

[0012] In combination with the first aspect, in certain implementations of the first aspect, determining that another perception entity performs a first perception service is performed based on the first configuration information and the location information of the perception target, including: determining a first distance, the first distance being the distance between the first perception target and the first perception entity; when the first distance is greater than or equal to a first threshold, determining that another perception entity performs the first perception service.

[0013] In this technical solution, when it is determined that the current position of the first perception target has exceeded the perception range of the perception demand for the first perception service, another perception entity can be determined to perform the first perception service. That is, when the first perception target moves out of the perception range of the first perception entity for the service demand of the first perception service, the first perception service may be interrupted. At this time, it is necessary to determine another perception entity to execute the first perception service to ensure the continuity of the first perception service.

[0014] In combination with the first aspect, in certain implementations of the first aspect, first request information is generated based on first configuration information, and the first request information is used to request the second perception entity to perform the first perception service; the first request information is sent to the second perception entity.

[0015] In this technical solution, the first perception entity or the first network device can determine another perception entity (second perception entity) based on the first configuration information, and request the second perception entity to perform the first perception service through the first request information.

[0022] In combination with the first aspect, in some implementations of the first aspect, the first perception entity receives second request information from the second perception entity or the first network device; and stops executing the first perception service according to the second request information.

[0023] In the present application, the first sensing target is in a mobile state.

In this case, the first sensing entity can determine that the first sensing target has entered the sensing range of the second sensing entity for the business needs of the first sensing service based on the second sensing entity or the first network device, thereby stopping the execution of the first sensing service.

[0115] First, a network architecture applicable to the embodiments of the present application is briefly introduced as follows.

[0116] Figure 1 1 is a schematic diagram of a wireless communication system 100 applicable to an embodiment of the present application. Figure 1 As shown, the wireless communication system 100 may include at least one network device, such as Figure 1 The wireless communication system 100 may further include at least one terminal device, such as Figure 1 The terminal device 120 and the terminal device 130 shown in the figure. Both the network device and the terminal device can be configured with multiple antennas, and the network device and the terminal device can communicate using multi-antenna technology. The terminal devices can also communicate with each other. For example, the terminal devices can communicate directly with each other. For another example, the terminal devices can communicate with each other through other communication devices, such as network devices or other terminal devices.

[0117] When the network device and the terminal device communicate, the network device can manage one or more cells, and there can be an integer number of terminal devices in a cell. Optionally, the network device 110 and the terminal device 120 form a single-cell communication system, and without loss of generality, the cell is referred to as cell #1. The network device 110 can be a network device in cell #1, or the network device 110 can serve a terminal device (such as terminal device 120) in cell #1.

[0118] It should be noted that a cell can be understood as an area within the coverage of wireless signals of network equipment.

[0119] It should be understood that Figure 1 The simplified schematic diagram is provided for ease of understanding. The wireless communication system 100 may also include other network devices or other terminal devices. Figure 1 The embodiments of the present application can be applied to any communication scenario in which a transmitting device and a receiving device communicate with each other.

[0120] In order to facilitate understanding of the embodiments of the present application, the terms involved in the embodiments of the present application are briefly explained below.

[0121] 1. Integrated sensing and communication (ISAC):

[0122] In the field of communication, the two functions of communication and perception can be integrated together, so that the communication system has both communication and perception functions, supporting both information transmission through wireless channels and perceiving the physical characteristics of the surrounding environment by actively recognizing and analyzing the characteristics of the channels, so as to achieve mutual enhancement of communication and perception functions. In the communication fusion perception technology, the perception signal can be sent by the perception device, and the signal (also called echo signal) reflected by the perceived target after the sent perception signal is received to determine the attribute information of the perceived target. For example, the speed, distance, shape, size and other information of the perceived target. The perceived target can be a fixed object, such as mountains, forests or buildings, or a movable object, such as a vehicle, a drone, a pedestrian, or a terminal device. Among them, the perception device can also be called a perception device, or a detector, etc., or a communication device with a perception function (such as a terminal device or an access network device, etc.). The perception function can at least include the ability to send a perception signal and receive an echo signal of the perception signal.

[0123] 2. Self-perception:

[0124] In this application, self-perception refers to the perception measurement of the perception target by receiving the perception signal emitted by itself. For example, in wireless communication, self-perception can include the perception of transmission power, the perception of signal quality, etc. For example, the transmitter transmits a perception signal, and the perception signal is received by the transmitter after being reflected by the perception target. The transmitter can obtain the distance of the perception target based on the transmission time and reception time of the perception signal. Self-perception technology has applications in many fields, such as smart transportation, smart cities, smart homes, etc. Self-perception can also be called a single-station perception mode. From the perspective of the perception signal process, the perception site must both send a perception signal and receive the signal reflected by the perception signal on the target surface. Therefore, the single-station perception mode is also called a self-transmitting and self-receiving mode.

[0125] 3. Perception of separation of sending and receiving:

[0126] In this application, the transmission and reception separation perception refers to the two functions of receiving and sending being performed independently. The transmission and reception separation perception can achieve better signal reception and transmission effects, and can also reduce the system complexity and improve the system stability. For example, the transmission and reception separation perception system includes two parts: the transmitter and the receiver. The transmitter is responsible for transmitting the perception signal, which is received by the receiver after being reflected by the perception target. The receiver processes the perception signal to obtain the information of the perception target. The transmission and reception separation perception technology has applications in many fields, such as wireless communication, satellite communication, radar, etc. This technology can improve the transmission efficiency and reliability of the communication system, and can also reduce the complexity and cost of the system. The transmission and reception separation perception can also be called the dual-station perception mode. From the perspective of the perception signal process, the transmitter and receiver of the perception signal are two different devices. From the perspective of the perception signal process, after the perception site A sends the perception signal, the signal reflected on the target surface is received by the perception site B. Therefore, the dual-station perception mode is also called the A send B receive mode.

[0127] It can be understood that in a single-station perception scenario, the access network device can send and receive signals by itself, or the terminal device can send and receive signals by itself. In a dual-station perception scenario, the access network device A can send and the access network device B can receive signals, the access network device can send and the UE can receive signals, the UE can send and the access network device can receive signals, or UE#1 can send and the access network device can receive signals.

[0128] Figure 2 It is a schematic diagram of a perception scenario applicable to an embodiment of the present application. Figure 2 Six perception scenarios are shown in FIG.

[0129] in, Figure 2 (a) shows a sensing scenario in which access network device A transmits and receives the sensing signal on its own. Access network device A transmits a sensing signal, and access network device A receives a reflected signal generated when the sensing signal encounters a target in the environment, thereby sensing information such as the position and speed of the target. Figure 2 (b) shows a perception scenario where access network device A sends and receives signals from access network device B. Access network device A transmits a perception signal, and access network device B receives a reflection signal generated when the perception signal encounters a target in the environment, and then access network device B perceives information such as the position and speed of the target. Figure 2 (c) shows the perception scenario of access network device A sending and receiving by terminal device. Access network device A transmits a perception signal, and the terminal device receives a reflection signal generated by the perception signal encountering a target in the environment, and then the terminal device perceives information such as the position and speed of the target.

[0130] in, Figure 2(d) shows a UE self-transmitting and self-receiving perception scenario, where UE#1 transmits a perception signal, and UE#1 receives a reflected signal generated when the perception signal encounters a target in the environment, thereby perceiving information such as the position and speed of the target. Figure 2 (e) shows the perception scenario of UE#1 sending and receiving access network devices. UE#1 transmits a perception signal, and access network device B receives a reflection signal generated by the perception signal encountering a target in the environment, and then access network device B perceives the target's position, speed and other information. Figure 2 (f) shows the perception scenario of UE#1 sending and UE#2 receiving. UE#1 transmits a perception signal, and UE#2 receives a reflection signal generated by the perception signal encountering a target in the environment, and then UE#2 perceives the target's position, speed and other information.

[0131] The above perception scenarios are merely illustrative and do not limit the embodiments of the present application.

[0132] In this application, the sensed target includes various tangible objects in the environment that can reflect electromagnetic waves, such as mountains, forests, or buildings, and can also include movable objects such as vehicles, drones, pedestrians, and terminal devices. The sensed target can also be called a target, a detected target, a sensed object, a detected object, or a sensed device, etc., which is not limited in the embodiments of this application.

[0133] Figure 3 It is a schematic diagram of a network architecture applicable to an embodiment of the present application.

[0134] like Figure 3 As shown, the network architecture includes but is not limited to the following network elements:

[0135] 1. Network exposure function (NEF) network element:

[0136] It is used to securely open the services and capabilities provided by 3GPP network functions to the outside world, and mainly supports the secure interaction between 3GPP networks and third-party applications.

[0137] 2. Application function (AF) network element:

[0138] Used to perform data routing affected by applications, access network open functional network elements, or interact with the policy framework for policy control, such as influencing data routing decisions, policy control functions, or providing some third-party services to the network side.

[0139] 3. Access and Mobility Management Function (AMF) network element:

[0140] It is mainly used for mobility management and access management, etc. It can be used to implement other functions of the mobility management entity (MME) in the LTE system except session management, such as legal interception and access authorization / authentication. When the AMF network element provides services for a session in a user device, it will provide storage resources of the control plane for the session to store the session identifier, the SMF network element identifier associated with the session identifier, etc. In the embodiment of the present application, it can be used to implement the functions of the access and mobility management network element.

[0141] 4. User plane function (UPF) network element:

[0142] It can be used for packet routing and forwarding, or quality of service (QoS) processing of user plane data. User data can access the data network (DN) through this network element, and can also receive user data from the data network and transmit it to the user equipment through the access network equipment. The transmission resources and scheduling functions that provide services to user equipment in the UPF network element are managed and controlled by the SMF network element. In the embodiment of the present application, it can be used to implement the functions of the user plane network element.

[0143] 5. Access equipment (radio access network, AN):

[0144] The access device in the embodiment of the present application may be a device for communicating with a user device. The access device may also be referred to as an access network device or a wireless access network device. For example, the access device may be an evolved NodeB (eNB or eNodeB) in an LTE system, or a wireless controller in a cloud radio access network (CRAN) scenario, or the access device may be a relay station, an access point, a vehicle-mounted device, a wearable device, an access device in a 5G network, or an access device in a future evolved PLMN network, etc. It may be an access point (AP) in a WLAN, or a gNB in ​​an NR system. The embodiment of the present application is not limited. Figure 3 Two RAN devices, namely RAN1 and RAN2, are shown in FIG.

[0145] In addition, in the embodiment of the present application, the access device is a device in the RAN, or in other words, a RAN node that connects the user equipment to the wireless network. For example, as an example and not a limitation, the access device may include: gNB, transmission reception point (TRP), evolved Node B (eNB), radio network controller (RNC), Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home evolved Node B, or home Node B, HNB), base band unit (BBU), or wireless fidelity (Wifi) access point (AP), etc. In a network structure, the network device may include a centralized unit (CU) node, or a distributed unit (DU) node, or a RAN device including a CU node and a DU node, or a RAN device including a control plane CU node (CU-CP node) and a user plane CU node (CU-UP node) and a DU node.

[0146] The access device provides services for the cell, and the user equipment communicates with the access device through the transmission resources used by the cell (for example, frequency domain resources, or spectrum resources). The cell may be a cell corresponding to the access device (for example, a base station), and the cell may belong to a macro base station or a base station corresponding to a small cell. The small cells here may include: metro cells, micro cells, pico cells, femto cells, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

[0147] In addition, multiple cells can work at the same frequency on a carrier in an LTE system or a 5G system. In some special scenarios, the above-mentioned carrier and cell concepts can also be considered equivalent. For example, in a carrier aggregation (CA) scenario, when a secondary carrier is configured for a UE, the carrier index of the secondary carrier and the cell identification (cell ID) of the secondary cell working on the secondary carrier are carried at the same time. In this case, the concepts of carrier and cell can be considered equivalent, for example, user equipment accessing a carrier is equivalent to accessing a cell.

[0148] The communication system of the present application can also be applied to vehicle to everything (V2X) technology, that is, the user device of the present application can also be a car, for example, a smart car or an autonomous driving car.

[0149] The "X" in V2X stands for different communication targets. V2X can include but is not limited to: vehicle to vehicle (V2V), vehicle to infrastructure (V2I), vehicle to network (V2N), and vehicle to pedestrian (V2P).

[0150] In V2X, the access device can configure a "zone" for the UE. The zone can also be called a geographic zone. When the zone is configured, the world will be divided into multiple zones, which are defined by reference points, length, and width. When the UE determines the zone identifier (ID), it will use the length, width, number of zones on the length, number of zones on the width, and reference points for the remaining operations. The above information can be configured by the access device.

[0151] V2X services can be provided in two ways: namely, based on the proximity-based services communication 5 (PC5) interface and based on the Uu interface. The PC5 interface is an interface defined on the basis of the sidelink, using which communication devices (e.g., cars) can communicate directly with each other. The PC5 interface can be used in out of coverage (OOC) and in coverage (IC), but only authorized communication devices can use the PC5 interface for transmission.

[0152] The access network device in the present application has a sensing capability, and can act as a sensing entity to send a sensing signal to a sensing target and receive a sensing echo signal. The echo signal can also be received by other sensing entities, or the echo signal of the sensing signal sent by other sensing entities can also be received. For details, please refer to Figure 2 The scenario in this application is not limited to this.

[0153] 6. Sensing service control function (SSCF):

[0154] The main function of SSCF is to receive capability registrations from sensing entities and implement orchestration of sensing services.

[0155] During the capability registration phase of the perception entity, the perception entity may send a capability registration request message to the SSCF, which includes the indication information of the perception entity and the indication information of the perception entities adjacent to the perception entity, the location information of the perception entity, the perception range of the perception entity and other parameters. After completing the registration, the SSCF may send a perception capability registration response message to the perception entity to notify the perception entity to complete the registration of the perception capability.

[0156] The indication information of the sensing entity may be an identifier or a name of the sensing entity, which is not limited in the embodiment of the present application.

[0157] During the orchestration stage of the perception service, SSCF can determine the sending entity and receiving entity of the perception signal based on service requirements. For example, SSCF can select a suitable perception entity as the sending entity based on the perception service request, and send a perception control message to RAN, which may include the perception signal Tx, the perception type, the KPI of the perception service, etc.; similarly, SSCF can select a suitable perception entity as the receiving entity based on the perception service request, and send a perception control message to UE, which may include the perception signal Rx, the perception type, etc.

[0158] SSCF can communicate with other NFs through a service based interface (SBI).

[0159] 7. Sensing data process function (SDPF):

[0160] SDPF is used to process perception service data.

[0161] The perception entity can send the perception raw data to the SDPF, the SDPF can calculate the perception measurement data based on the perception raw data, calculate the perception result based on the perception measurement data, and send the processed result to the DN. For example, it can be sent to the DN via the NEF or gateway (gateway, GW), which is not limited to this in the embodiments of the present application.

[0162] SDPF can be attached to the SBI bus or a separate interface can be defined.

[0163] In the present application, the RAN can be directly connected to the SSCF or forwarded through the AMF, which is not limited in the embodiments of the present application.

[0164] In the present application, the perception data of the RAN or UE may be forwarded to the SDPF via the UPF, or may be directly sent to the SDPF, which is not limited in the embodiments of the present application.

[0165] It should be understood that all the network architectures shown above are only exemplary illustrations, and the network architectures applicable to the embodiments of the present application are not limited thereto. Any network architecture that can implement the functions of the above-mentioned network elements is applicable to the embodiments of the present application.

[0166] It should also be understood that the functions or network elements shown in the figure can be understood as network elements for implementing different functions, for example, they can be combined into network slices as needed. These network elements can be independent devices, or they can be integrated into the same device to implement different functions, or they can be network elements in hardware devices, or they can be software functions running on dedicated hardware, or they can be virtualized functions instantiated on a platform (for example, a cloud platform). This application does not limit the specific form of the above network elements.

[0167] It should also be understood that the above naming is only defined for the convenience of distinguishing different functions and should not constitute any limitation to this application. This application does not exclude the possibility of using other naming in 6G networks and other future networks. For example, in a 6G network, some or all of the above network elements may use the terminology in 5G, or may use other names, etc.

[0168] In this application, in a wireless sensing service scenario involving multiple sensing entities, multiple sensing entities collect data and collaborate to complete the sensing service. Due to the mobility of the sensing target, when it moves out of the effective sensing range of the current sensing entity within the coverage of the sensing service, the continuity of the sensing service needs to be guaranteed.

[0169] In view of this, an embodiment of the present application provides a communication method for perception, which can ensure the continuity of wireless perception services when the perception target moves.

[0170] The communication method provided by the embodiment of the present application will be described in detail below with reference to the accompanying drawings. The embodiment provided by the present application can be applied to the above Figure 1 The communication system shown is not limited.

[0171] The solution of this application is described in detail below.

[0172] Figure 4 It is a scenario schematic diagram applicable to an embodiment of the present application.

[0173] The scenario may include SDPF and SSCF.

[0174] The scene can also include multiple perceptual entities, such as Figure 4 The SE shown in a , S.E. b , S.E. c , the three sensing entities each have a sensing service range.

[0175] The sensing service range of each sensing entity can be understood as an effective sensing coverage area, that is, within the coverage range, the sensing entity can generate effective sensing data for the sensing target. Once the sensing target exceeds the sensing range, the sensing data can be considered invalid.

[0176] In the present application, the perception service range of the perception entity is determined according to its respective performance, and the perception service range may be an irregular area. For ease of understanding, the perception service range of the perception entity in the present application is illustrated using a circular area as an example.

[0177] In this application, the maximum effective perception distance R relative to the perception entity is determined based on the performance of the perception entity. max .like Figure 4 As shown in a The perceived service scope is SE a The position of the circle is the center, with R max1 Circular area with radius #1; SE b The perceived service scope is SE b The position of the circle is the center, with R max2 Circular area with radius #2; SE c The perceived service scope is SE c The position of the circle is the center, with R max3 When the target moves in area #1, SE a The sensing target can be sensed and the sensing data can be sent to the SDPF; when the sensing target moves in area #2, the SE b The sensing target can be sensed and the sensing data can be sent to the SDPF; when the sensing target moves in area #3, the SE cThe perception of the perception target can be performed and the perception data can be sent to the SDPF.

[0178] In this application, the SSCF can determine the effective distance R to ensure the continuity of the perception service based on the service requirements of the perception service. t .like Figure 4 As shown in a The service scope of the perceived business continuity service is SE a The position of the circle is the center, with R t1 A circular area with radius #1';SE b The service scope of the perceived business continuity service is SE b The position of the circle is the center, with R t2 A circular area with radius #2';SE c The service scope of the perceived business continuity service is SE c The position of the circle is the center, with R t3 When the target moves in area #1', SE a The sensing target can be sensed and the sensing service can be ensured to be continuous; when the sensing target moves in area #2', SE b The sensing target can be sensed and the sensing service can be ensured to be continuous; when the sensing target moves in area #3', SE c Awareness of the awareness target can be performed and awareness service continuity can be ensured.

[0179] Among them, SSCF can determine the effective distance R to ensure the continuity of the perception service based on the service KPI of the perception service. t The distance between the sensing target and the sensing entity does not exceed R t When the distance between the sensing target and the sensing entity exceeds R t When this happens, the continuity of the perceived service may be affected.

[0180] It should be noted that in this application, the effective distance R to ensure the continuity of the perceived service is t The maximum effective perception distance R from the perception entity max Different, once the perception target moves out of the perception service continuity service range, the continuity of the perception service may have been affected, but it may still be within the perception service range. Although the perception data of the perception entity is valid, the continuity of the perception service cannot be guaranteed due to reasons such as weak signal quality or large changes in signal quality.

[0181] In this application, the effective distance R to ensure the continuity of the perceived service t It can also be called the maximum scope of the business requirements of the sensing entity for the sensing business.

[0182] The following is a detailed description of the effective distance R based on the guarantee of the perceived service continuity. t Ways to ensure perceived business continuity.

[0183] Figure 5 It is a schematic diagram of a communication method for perception applicable to the embodiment of the present application. For ease of description, the method 500 is exemplarily described by taking the interaction between the execution subject being the first perception entity / first network device and the second network device and the second perception entity as an example.

[0184] In the present application, the perception entity may include access network equipment, terminal equipment and other devices with perception capabilities. When the perception target moves in a scenario where multiple perception entities cooperate in perception, the multiple perception entities can perceive the perception target within their respective perception ranges. In the present application, the multiple perception entities take the first perception entity and the second perception entity as examples, and of course can also include a third perception entity, etc., which is not limited to the embodiments of the present application.

[0185] Exemplarily, the first network device is a network entity having a perception data processing function, such as an SDPF.

[0186] Exemplarily, the second network device is a network entity having an awareness service control function, such as SSCF.

[0187] S510, a first perception entity or a first network device receives first configuration information.

[0188] In the present application, the second network device may send first configuration information to the first network device or the first perception entity.

[0189] The first configuration information includes a first threshold, and the first threshold is used to indicate the perception range of the first perception entity for the first perception service. It should be noted that the perception range for the first perception service is related to the service demand of the first perception service. For example, the higher the service demand (such as service quality requirement) of the first perception service, the smaller the perception range for the first perception service.

[0190] In one possible implementation, the second network device may also send the first configuration information to a perception entity adjacent to the first perception entity, for example, send the first configuration information to the second perception entity, and the first configuration information may also include a second threshold, and the second threshold is used to indicate the perception range of the second perception entity for the first perception service.

[0191] The first threshold and the second threshold can also be understood as the effective distance for ensuring the service continuity of the first sensing service, that is, R t .

[0192] In the present application, the first threshold and the second threshold are determined by the second network device for the first perception entity and the second perception entity respectively based on the service requirements of the first perception service.

[0193] Exemplarily, the second network device determines the first threshold and the second threshold based on a service key performance indicator (KPI) of the first perceived service.

[0194] It can be understood that the business requirements of the same perception service (for example, the first perception service) may be different for different perception entities, and therefore the effective distance for ensuring business continuity may also be different. Of course, the effective distances for different perception entities may also be the same, that is, the first threshold and the second threshold may be the same or different, and the embodiments of the present application do not limit this.

[0195] In the present application, the first configuration information may also include information of a third sensing entity adjacent to the first sensing entity, for example, the first configuration information may also include a third threshold, and the first configuration information is sent to the third sensing entity. The present application embodiment does not limit this.

[0196] S520: The first perception entity / first network device determines another perception entity to perform the first perception service according to the first configuration information and the location information of the first perception target.

[0197] In the present application, when the first perception target moves within the perception range of the first perception entity to ensure the continuity of the perception service, the first perception service can be realized based on the perception of the first perception target, that is, the service requirements of the first perception service are met. The first perception entity or the first network device can determine whether the first perception target is currently within the perception range of the first perception entity to ensure the continuity of the perception service based on the location information of the first perception target. The location information of the first perception target is used to indicate the location of the first perception target, for example, it can be the distance information between the first perception target and the first perception entity (or other perception entity), or the physical location coordinate information of the first perception target, or it can be the location information of the first perception target in the signal strength distribution map determined according to the signal strength between it and the first perception entity (or other perception entity), or it can be other information that can represent the physical location of the first perception target or the location of the signal distribution map.

[0198] Exemplarily, the position information of the first sensing target includes a first distance. The first distance is the distance between the position of the first sensing target and the position of the first sensing entity.

[0199] In one possible implementation, the first perception entity or the first network device determines that the first distance exceeds the effective distance for the first perception entity (i.e., the first perception entity) to ensure the continuity of the perception service, and the service continuity of the first perception service may not be able to be maintained. It can be determined that other perception entities execute the first perception service.

[0200] It can be understood that the first perception target is in a mobile state. When the first perception target has moved out of or is about to move out of the perception range that ensures the business continuity of the perception service, in this case, another perception entity can be determined to execute the first perception service to ensure the continuity of the first perception service.

[0201] In a possible implementation, the first perception entity / first network device determines a first distance, and when the first distance is greater than or equal to a first threshold, determines that another perception entity performs a first perception service.

[0202] The first distance is the distance between the first perception target and the first perception entity;

[0203] The first sensing entity may determine the first distance based on the sensing capability.

[0204] Among them, the first network device can obtain the first distance through the first sensing entity.

[0205] The following is an exemplary description of how to determine another perceptual entity.

[0206] In one possible implementation, the first perception entity / first network device may determine the first request information based on the first configuration information.

[0207] The first request information is used to request the second perception entity to perform the first perception service.

[0208] Furthermore, the first perception entity / first network device may send the first request information to the second perception entity.

[0209] Exemplarily, the first perception entity / first network device may determine the target perception entity, that is, the second perception entity, based on an algorithm, which is not limited in the embodiments of the present application.

[0210] Among them, the first request information may include indication information of the first perception service, indication information of the first perception entity (for example, the identifier or name of the first perception entity), indication information of the second perception entity (for example, the identifier or name of the second perception service) and perception information.

[0211] In the present application, the indication information of the first perception service, for example, can be the identifier or name of the first perception service, or other information indicating the first perception service, which is not limited in the present application; the indication information of the first perception entity, for example, can be the identifier or name of the first perception entity, or other information indicating the first perception entity, which is not limited in the present application; the indication information of the second perception entity, for example, can be the identifier or name of the second perception entity, or other information indicating the second perception entity, which is not limited in the present application. This will not be repeated in the following text.

[0212] In the present application, the first perception entity or the first network device can determine another perception entity to perform the first perception service based on the first configuration information.

[0213] Among them, when the first perceptual entity determines another perceptual entity based on the first configuration information, in one possible manner, the first configuration information may also include indication information of the perceptual entity (for example, the identifier or name of the perceptual entity) and a first discrimination mode. The indication information of the perceptual entity includes indication information of the first perceptual entity and indication information of perceptual entities adjacent to the first perceptual entity, for example, the identifier of the first perceptual entity, the identifier of the second perceptual entity, and the identifier of the third perceptual entity. The first discrimination mode is used to instruct the first perceptual entity to determine another perceptual entity.

[0214] It can be understood that the first discrimination mode instructs the first sensing entity to determine another sensing entity to perform the first sensing service, and the first sensing entity can determine another sensing entity based on the sensing capability information and location information of the adjacent sensing entities.

[0215] Exemplarily, the first configuration information may also include the maximum effective perception distance of the second perception entity and the third perception entity and the location information of the second perception entity and the third perception entity.

[0216] Among them, when the first network device determines another perception entity based on the first configuration information, in another possible manner, the first configuration information may also include indication information of the perception entity identifier (for example, the identifier or name of the perception entity) and a second discrimination mode, and the indication information of the perception entity includes indication information of the first perception entity and indication information of perception entities adjacent to the first perception entity, for example, the identifier of the first perception entity, the identifier of the second perception entity, and the identifier of the third perception entity. The second discrimination mode is used to instruct the first network device to determine another perception entity.

[0217] It can be understood that the second discrimination mode instructs the first network entity to determine another perception entity to perform the first perception service, and the first network device can determine another perception entity based on the perception capability information and location information of the perception entity adjacent to the first perception entity.

[0218] Exemplarily, the first configuration information may also include the maximum effective perception distance of the second perception entity and the third perception entity and the location information of the second perception entity and the third perception entity.

[0219] In the present application, the second perception entity receives the first request information and performs perception of the first perception target according to the first request information.

[0220] It can be understood that the first perception target may be in a moving state. When the first perception target has entered the perception range of the second perception entity for the business needs of the first perception business, the first perception entity may stop perception.

[0221] In the present application, the second perception entity or the first network device can determine whether the first perception target is currently within the perception range of the second perception entity to ensure the continuity of the perception service based on the location information of the first perception target.

[0222] Exemplarily, the position information of the first sensing target includes a second distance. The second distance is the distance between the position of the first sensing target and the position of the second sensing entity.

[0223] In one possible implementation, when the second perception entity or the first network device determines that the second distance is less than the second threshold, a second request message may be sent to the first perception entity, where the second request message is used to request the first perception entity to stop executing the first perception service.

[0224] It can be understood that the second perception entity can judge by itself that the first perception target has entered the perception range of the second perception entity for the business needs of the first perception service, or the first network device can judge based on the perception data that the first perception target has entered the perception range of the second perception entity for the business needs of the first perception service, thereby instructing the second perception entity to stop perception.

[0225] Correspondingly, the first perception entity receives the second request information sent by the second perception entity or the first network device, and stops executing the first perception service.

[0226] It should be understood that before the first sensing entity receives the second request information, both the first sensing entity and the second sensing entity sense the first sensing target and send sensing data to the SDPF.

[0227] For example, Figure 4 As shown in , when the perception target moves out of area 1' and is about to enter area 2', and moves between area 1' and area 2', the first perception entity and the second perception entity simultaneously perform the first perception service. When the perception target enters area 2', that is, the second distance is less than the second threshold, the first perception entity can stop performing the first perception service.

[0228] In the present application, when the first perception entity or the first network device determines another perception entity, it can also request the second network device to determine the second perception entity.

[0229] In a possible implementation, the first perception entity / first network device may send third request information to the second network device, where the third request information is used to request the second network device to determine the second perception entity.

[0230] The third request information includes indication information of the first perception service, indication information of the first perception entity and perception information.

[0231] Among them, the first configuration information also includes indication information of the first perception service and a third determination mode, and the third determination mode is used to instruct the second network device to determine the second perception entity.

[0232] It can be understood that the third determination mode instructs the second network device to determine another perception entity to perform the first perception service, and the second network device can determine the other perception entity based on the perception capability information and location information of the perception entity adjacent to the first perception entity.

[0233] It should be noted that the second network device can obtain indication information (for example, identification or name of each perception service), perception capability information and location information of the first perception entity and perception entities adjacent to the first perception entity during the registration phase.

[0234] Exemplarily, the second network device may obtain the maximum effective perception distances of the first perception entity, the second perception entity, and the third perception entity, and the location information of the second perception entity and the third perception entity.

[0235] In the present application, the second network device can determine the target perception entity, that is, the second perception entity, according to an algorithm, and the embodiments of the present application are not limited to this.

[0236] In a possible implementation, the second network device sends fourth request information to the second perception entity, where the fourth request information is used to request the second perception entity to perform the first perception service.

[0237] Among them, the fourth request information includes indication information of the first perception service, indication information of the first perception entity, indication information of the second perception entity and perception information.

[0238] In the present application, the second perception entity receives the fourth request information and performs perception of the first perception target according to the fourth request information.

[0239] It can be understood that the first perception target may be in a moving state. When the first perception target has entered the perception range of the second perception entity for the business needs of the first perception business, the first perception entity may stop perception.

[0240] In one possible implementation, when the second perception entity determines that the second distance is less than the second threshold, the second perception entity may send a second request message to the first perception entity, where the second request message is used to request the first perception entity to stop executing the first perception service; it may also send a fifth request message to the second network device, where the fifth request message is used to request the first perception entity to stop executing the first perception service, and the second network device may send a sixth request message to the first perception device, where the sixth request message is used to request the first perception entity to stop executing the first perception service.

[0241] The second distance is the distance between the first perception target and the second perception entity.

[0242] Correspondingly, the first perception entity receives the second request information or the sixth request information sent by the second perception entity or the second network device, and stops executing the first perception service.

[0243] It should be understood that before the first perception entity receives the second request information or the sixth request information, the first perception entity and the second perception entity simultaneously perceive the first perception target and send perception data to the SDPF.

[0244] In the present application, the first perception entity and the second perception entity may be access network devices or terminal devices, the first network device may be a perception data processing function, and the second network device may be a perception service control function.

[0245] In the above scheme, it is explained that the first perception entity or the first network device determines another perception entity to perform the first perception service based on the effective distance of the service demand for the first perception service. Next, the specific schemes for different scenarios are described in detail.

[0246] First, an exemplary scheme in which a first sensing entity determines another sensing entity to perform a first sensing service is introduced.

[0247] Figure 6 It is a schematic diagram of a communication method for perception applicable to an embodiment of the present application.

[0248] In this embodiment, the perception entities include perception entity #1, perception entity #2, and perception entity #3; the first network device takes SDPF as an example, the second network device takes SSCF as an example, and the first perception service takes perception service #A as an example.

[0249] The method 600 may specifically include the following steps.

[0250] S610, SSCF sends configuration information #1 to perception entity #1, perception entity #2 and perception entity #3.

[0251] Configuration information #1 may include indication information of sensing service #A, indication information of sensing entity #1, indication information of sensing entity #2, indication information of sensing entity #3, and sensing scope of all sensing entities for the service requirements of sensing service #A (R of sensing entity #1). t1 , R of perceived entity #2 t2 , R of perceived entity #3 t3 ).

[0252] Among them, the indication information of perception service #A, for example, can be the identifier or name of perception service #A; the indication information of perception entity #1, for example, can be the identifier or name of perception entity #1; the indication information of perception entity #2, for example, can be the identifier or name of perception entity #2.

[0253] In the following, to avoid repetition, the indication information of perception service #A takes the identifier of perception service #A as an example, the indication information of perception entity #1 takes the identifier of perception entity #1 as an example, and the indication information of perception entity #2 takes the identifier of perception entity #2 as an example.

[0254] In an optional understanding, the SSCF sends the sensing scope of the service demand of the sensing entity #1 and the adjacent sensing entities for the sensing service #A to each sensing entity.

[0255] The sensing scope of the sensing entity #1 and the adjacent sensing entities for the service requirements of the sensing service #A is sent to each sensing entity through the configuration information #1. That is, the configuration information #1 may include the service identifier of the sensing service #A, the identifier of the sensing entity #1, the identifier of the sensing entity #2, the identifier of the sensing entity #3, and the identifier of the sensing entity #4. t1 , R t2 , R t3 ).

[0256] Among them, R t1 is an example of the first threshold, which is used to indicate the sensing range of the sensing entity #1 for the service demand of the sensing service #A; R t2 is an example of the second threshold, which is used to indicate the sensing range of the sensing entity #2 for the service demand of the sensing service #A; R t3 This is an example of the third threshold, which is used to indicate the perception range of the service demand of the perception entity #3 for the perception service #A.

[0257] It should be understood that the above R t1 , R t2 , R t3It is determined by SSCF based on the business needs of perception service #A, that is, when the perception target moves out of the perception range corresponding to the current perception entity that ensures the continuity of the perception service, the business continuity may be affected. At this time, the perception data of the current perception entity may be invalid. In this case, it can be determined that another perception entity will continue to execute the perception service #A.

[0258] It can be understood that the maximum perception range of the perception entity is larger than the perception range for ensuring the continuity of the perception business. The perception target moves out of the perception range for ensuring the continuity of the perception business, but is still within the maximum perception range of the perception entity. At this time, due to the distance problem of the perception target, the continuity of the perception business may not be guaranteed, and the perception data of the perception entity may also be invalid.

[0259] The configuration information #1 may also include a determination mode #1, where the determination mode #1 is used to instruct the perception entity #1 to determine another perception entity to perform the perception service #A.

[0260] The configuration information #1 may also include the maximum effective sensing distance R of the sensing entity #1. max1 , the maximum effective sensing distance R of sensing entity #2 max2 , the maximum effective sensing distance R of sensing entity #3 max3 .

[0261] Among them, configuration information #1 can also include location information of perception entity #1, perception entity #2, and perception entity #3.

[0262] S620, perception entity #1, perception entity #2 and perception entity #3 send a response message #1 to the SSCF.

[0263] After receiving configuration information #1, each perception entity may send a response message #1 to the SSCF.

[0264] S630, the sensing entity #1 determines that the sensing entity #2 executes the sensing service #A according to the configuration information #1 and the location information of the sensing target.

[0265] SSCF can activate perception entity #1 to perform perception service #A. For example, SSCF can determine that perception entity #1 can be activated to perform perception service #A based on the business requirements of perception service #A and the location information of the current perception target.

[0266] Sensing entity #1 executes sensing service #A and sends sensing data to SDPF.

[0267] Based on the perception data, the perception entity #1 determines that the distance between the current perception target and the position of the perception entity #1 is R1. When R1 is greater than or equal to R t1When the sensing entity #1 determines that the sensing service #A is performed by another sensing entity.

[0268] It can be understood that when R1 is greater than or equal to R t1 When the perception entity #1 determines that the perception target has moved out of or is about to move out of the perception range that ensures the business continuity of the perception service, in this case, another perception entity can be determined to execute the perception service #A to ensure the continuity of the perception service #A.

[0269] Exemplarily, perception entity #1 may determine perception entity #2 to perform perception service #A according to an algorithm.

[0270] It can be understood that the perception entity #1 can determine the perception entity that performs the perception service #A based on the maximum effective perception distances of the perception entities #2 and #3 and the location information of the perception entities #2 and #3.

[0271] Perception entity #1 may also determine perception entity #2 in other ways, which is not limited in this embodiment of the present application.

[0272] S640, perception entity #1 sends request information #1 to perception entity #2.

[0273] Request information #1 is used to request the perception entity #2 to execute the perception service #A.

[0274] Among them, the request information #1 may include the service identifier of the perception service #A, the identifier of the perception entity #1, the identifier of the perception entity #2, the perception information, etc.

[0275] S650, perception entity #2 executes perception service #A.

[0276] The sensing entity #2 performs the sensing service #A based on the request information #1.

[0277] Sensing entity #2 uploads the sensing data to SDPF.

[0278] When executing perception service #A, perception entity #2 can judge by itself that the perception target has entered the perception range of perception entity #2 for the business needs of the first perception service, or SDPF can judge based on the perception data that the perception target has entered the perception range of perception entity #2 for the business needs of the first perception service, thereby instructing perception entity #1 to stop perception.

[0279] Determining and instructing the sensing entity #1 to stop sensing through the sensing entity #2 may specifically include the following steps S660a and S670a. Determining and instructing the sensing entity #1 to stop sensing through the SDPF may include the following steps S660b and S670b.

[0280] S660a, the sensing entity #2 determines that R2 is less than or equal to R according to the configuration information #1. t2 .

[0281] Based on the perception data, the perception entity #2 determines that the distance between the current perception target position and the perception entity #2 position is R2. When R2 is less than or equal to R t2 , perception entity #2 determines that perception entity #1 can stop executing perception service #A.

[0282] It can be understood that when R2 is less than or equal to R t2 When the perception entity #2 detects that the perception target has entered the perception range of the business needs of the first perception service of the perception entity #2, in this case, it can be determined that another perception entity can stop executing the perception service #A, and the perception entity #2 can ensure the continuity of the perception service #A.

[0283] S660b, SDPF determines that R2 is less than or equal to R according to configuration information #1. t2 .

[0284] Based on the perception data of perception entity #2, SDPF determines that the distance between the current perception target position and the position of perception entity #2 is R2. When R2 is less than or equal to R t2 , SDPF determines that perception entity #1 can stop executing perception service #A.

[0285] It should be understood that the SSCF may send configuration information #1 to the SDPF and determine the R based on the configuration information #1. t2 .

[0286] In a possible implementation, perception entity #2 starts to execute perception service #A, sends a perception response message to SDPF, and SDPF determines that perception entity #1 can stop executing perception service #A.

[0287] Either step S660a or step S660b can be performed.

[0288] When perception entity #2 or SDPF determines that perception entity #1 can stop executing perception service #A, it can instruct perception entity #1 to stop executing perception service #A.

[0289] S670a, perception entity #2 sends request information #2 to perception entity #1.

[0290] Request information #2 is used to instruct perception entity #1 to stop executing perception service #A.

[0291] In a possible implementation, the sensing entity #2 may send a sensing response message to the sensing entity #1, and the sensing entity #1 stops executing the sensing service #A according to the response message.

[0292] Among them, the request information #2 may include the identifier of the perception service #A.

[0293] S670b, SDPF sends request information #2 to perception entity #1.

[0294] Request information #2 is used to instruct perception entity #1 to stop executing perception service #A.

[0295] Among them, the request information #2 may include the identifier of the perception service #A.

[0296] Either step S670a or step S670b can be performed.

[0297] S680, the perception entity #1 stops executing the perception service #A according to the request information #2.

[0298] Before receiving request information #2, perception entity #1 can execute perception service #A simultaneously with perception entity #2. When the perception target has entered the perception range where perception entity #2 can ensure the business continuity of the perception service, perception entity #1 stops executing perception service #A.

[0299] Based on the above technical solution, perception entity #1 can determine another perception entity to continue to perform the perception service based on the configured perception range that ensures the continuity of the perception service. When the perception target enters the perception range where another perception entity can ensure the business continuity of the perception service, perception entity #1 stops perceiving, thereby ensuring the continuous upload of effective perception data of the perception service, meeting the needs of the perception service, and improving the perception capability.

[0300] Next, an exemplary solution in which the SDPF determines another perception entity to perform a first perception service is introduced.

[0301] Figure 7 It is a schematic diagram of a communication method for perception applicable to an embodiment of the present application.

[0302] In this embodiment, the perception entities include perception entity #1, perception entity #2, and perception entity #3; the first network device takes SDPF as an example, the second network device takes SSCF as an example, and the first perception service takes perception service #A as an example.

[0303] The method 700 may specifically include the following steps.

[0304] S710, SSCF sends configuration information #2 to SDPF.

[0305] Configuration information #2 may include indication information of sensing service #A, indication information of sensing entity #1, indication information of sensing entity #2, indication information of sensing entity #3, and the sensing range of all sensing entities for the service requirements of sensing service #A (R of sensing entity #1, t1 , R of perceived entity #2 t2 , R of perceived entity #3 t3 ).

[0306] Among them, the indication information of perception service #A, for example, can be the identifier or name of perception service #A; the indication information of perception entity #1, for example, can be the identifier or name of perception entity #1; the indication information of perception entity #2, for example, can be the identifier or name of perception entity #2.

[0307] In the following, to avoid repetition, the indication information of perception service #A takes the identifier of perception service #A as an example, the indication information of perception entity #1 takes the identifier of perception entity #1 as an example, and the indication information of perception entity #2 takes the identifier of perception entity #2 as an example.

[0308] In an optional understanding, the SSCF sends the sensing scope of the service demand of the sensing entity #1 and the adjacent sensing entities for the sensing service #A to the SDPF.

[0309] The sensing scope of the sensing entity #1 and the adjacent sensing entities for the service requirements of the sensing service #A is sent to the SDPF through the configuration information #2. That is, the configuration information #2 may include the service identifier of the sensing service #A, the identifier of the sensing entity #1, the identifier of the sensing entity #2, and the identifier of the sensing entity #3. t1 , R t2 , R t3 ).

[0310] Among them, R t1 is an example of the first threshold, which is used to indicate the sensing range of the sensing entity #1 for the service demand of the sensing service #A; R t2 is an example of the second threshold, which is used to indicate the sensing range of the sensing entity #2 for the service demand of the sensing service #A; R t3 This is an example of the third threshold, which is used to indicate the perception range of the service demand of the perception entity #3 for the perception service #A.

[0311] It should be understood that the above R t1 , R t2 , R t3It is determined by SSCF based on the business needs of perception service #A, that is, when the perception target moves out of the perception range of the business needs of the perception service corresponding to the current perception entity, business continuity may be affected. At this time, the perception data of the current perception entity may be invalid. In this case, it can be determined that another perception entity will continue to execute the perception service #A.

[0312] It can be understood that the maximum perception range of the perception entity is larger than the perception range for ensuring the continuity of the perception business, or the perception range of the business needs of the perception business. The perception target moves out of the perception range for ensuring the continuity of the perception business, but is still within the maximum perception range of the perception entity. At this time, due to the distance problem of the perception target, the continuity of the perception business may not be guaranteed, and the perception data of the perception entity may also be invalid.

[0313] The configuration information #2 may also include a determination mode #2, where the determination mode #2 is used to instruct the SDPF to determine another perception entity to execute the perception service #A.

[0314] The configuration information #2 may also include the maximum effective sensing distance R of the sensing entity #1. max1 , the maximum effective sensing distance R of sensing entity #2 max2 , the maximum effective sensing distance R of sensing entity #3 max3 .

[0315] Among them, configuration information #2 can also include location information of perception entity #1, perception entity #2, and perception entity #3.

[0316] S720, SDPF sends a response message #2 to SSCF.

[0317] After receiving configuration information #2, SDPF may send response message #2 to SSCF.

[0318] S730, SDPF determines that perception entity #2 executes perception service #A according to configuration information #2 and location information of the perception target.

[0319] SSCF can activate perception entity #1 to perform perception service #A. For example, SSCF can determine that perception entity #1 can be activated to perform perception service #A based on the business requirements of perception service #A and the location information of the current perception target.

[0320] Sensing entity #1 executes sensing service #A and sends sensing data to SDPF.

[0321] SDPF can determine the distance between the current position of the perceived target and the position of the perceived entity #1 as R1 based on the perceived data. t1, SDPF determines that another perception entity shall perform perception service #A.

[0322] It can be understood that when R1 is greater than or equal to R t1 When , SDPF can determine that the perception target has moved out of or is about to move out of the perception range that ensures the business continuity of the perception service. In this case, another perception entity can be determined to execute perception service #A to ensure the continuity of the perception service #A.

[0323] Exemplarily, the SDPF may determine, based on an algorithm, the perception entity #2 to perform the perception service #A.

[0324] SDPF may also determine perception entity #2 in other ways, which is not limited in this embodiment of the present application.

[0325] S740, SDPF sends request information #1 to perception entity #2.

[0326] Request information #1 is used to request the perception entity #2 to execute the perception service #A.

[0327] Among them, the request information #1 may include the service identifier of the perception service #A, the identifier of the perception entity #1, the identifier of the perception entity #2, the perception information, etc.

[0328] S750, perception entity #2 executes perception service #A.

[0329] The sensing entity #2 performs the sensing service #A based on the request information #1.

[0330] Sensing entity #2 uploads the sensing data to SDPF.

[0331] When executing perception service #A, perception entity #2 can judge by itself that the perception target has entered the perception range that ensures the business continuity of the perception service, or SDPF can judge based on perception data that the perception target has entered the perception range that ensures the business continuity of the perception service, thereby instructing perception entity #1 to stop perception.

[0332] Determining and instructing the sensing entity #1 to stop sensing through the sensing entity #2 may specifically include the following steps S760a and S770a. Determining and instructing the sensing entity #1 to stop sensing through the SDPF may include the following steps S760b and S770b.

[0333] Specifically, it may include the following steps S760a and S760b.

[0334] S760a, the sensing entity #2 determines that R2 is less than R according to the configuration information #1. t2 .

[0335] Based on the perception data, the perception entity #2 determines that the distance between the current perception target position and the perception entity #2 position is R2. When R2 is less than or equal to R t2 , perception entity #2 determines that perception entity #1 can stop executing perception service #A.

[0336] It can be understood that when R2 is less than or equal to R t2 When the perception entity #2 determines that the perception target has entered the perception range that ensures the business continuity of the perception service, in this case, it can be determined that another perception entity can stop executing perception service #A, and perception entity #2 can ensure the continuity of the perception service #A.

[0337] S760b, SDPF determines that R2 is less than R according to configuration information #1. t2 .

[0338] Based on the perception data of perception entity #2, SDPF determines that the distance between the current perception target position and the position of perception entity #2 is R2. When R2 is less than or equal to R t2 , SDPF determines that perception entity #1 can stop executing perception service #A.

[0339] It should be understood that the SSCF may send configuration information #2 to the SDPF, and determine the R t2 .

[0340] In a possible implementation, perception entity #2 starts to execute perception service #A, sends a perception response message to SDPF, and SDPF determines that perception entity #1 can stop executing perception service #A.

[0341] Either step S760a or step S760b can be performed.

[0342] When perception entity #2 or SDPF determines that perception entity #1 can stop executing perception service #A, it can instruct perception entity #1 to stop executing perception service #A.

[0343] S770a, perception entity #2 sends request information #2 to perception entity #1.

[0344] Request information #2 is used to instruct perception entity #1 to stop executing perception service #A.

[0345] In a possible implementation, the sensing entity #2 may send a sensing response message to the sensing entity #1, and the sensing entity #1 stops executing the sensing service #A according to the response message.

[0346] Among them, the request information #2 may include the identifier of the perception service #A.

[0347] S770b, SDPF sends request information #2 to perception entity #1.

[0348] Request information #2 is used to instruct perception entity #1 to stop executing perception service #A.

[0349] Among them, the request information #2 may include the identifier of the perception service #A.

[0350] Either step S670a or step S670b can be performed.

[0351] S780, the perception entity #1 stops executing the perception service #1 according to the request information #2.

[0352] Before receiving request information #2, perception entity #1 can execute perception service #A simultaneously with perception entity #2. When the perception target has entered the perception range where perception entity #2 can ensure the business continuity of the perception service, perception entity #1 stops executing perception service #A.

[0353] Based on the above technical solution, SDPF, as a data processing network element, can determine another perception entity to continue to perform the perception service based on the configured perception range that ensures the continuity of the perception service and the perception data uploaded by the perception entity. When the perception target enters the perception range where another perception entity can ensure the business continuity of the perception service, perception entity #1 stops sensing, thereby ensuring the continuous upload of effective perception data of the perception service, meeting the needs of the perception service, and improving the perception capability.

[0354] Next, an exemplary scheme in which the SSCF determines another perception entity to perform a first perception service is introduced.

[0355] Figure 8 It is a schematic diagram of a communication method for perception applicable to an embodiment of the present application.

[0356] In this embodiment, the perception entities include perception entity #1, perception entity #2, and perception entity #3; the first network device takes SDPF as an example, the second network device takes SSCF as an example, and the first perception service takes perception service #A as an example.

[0357] The method 800 may specifically include the following steps.

[0358] S810, SSCF sends configuration information #3 to perception entity #1, perception entity #2 and perception entity #3.

[0359] Among them, configuration information #3 may include indication information of perception service #A, and for different perception entities, may also include the perception scope of each perception entity for the business requirements of perception service #A.

[0360] The indication information of the perception service #A may be, for example, the identifier or name of the perception service #A.

[0361] In the following, to avoid redundancy, the indication information of the perception service #A takes the identifier of the perception service #A as an example.

[0362] An optional understanding is that the SSCF sends the sensing scopes of the service requirements of the sensing service #A to different sensing entities respectively.

[0363] The configuration information #3 is used to send the perception scope of the service requirements of the perception service #A to different perception entities, that is, the configuration information #3 sent by the SSCF to the perception entity #1 may include the service identifier and R t1 ; The configuration information #3 sent by SSCF to the perception entity #2 may include the service identifier of the perception service #A and R t2 ; The configuration information #3 sent by SSCF to the perception entity #3 may include the service identifier of the perception service #A and R t3 .

[0364] Among them, R t1 is an example of the first threshold, which is used to indicate the sensing range of the sensing entity #1 for the service demand of the sensing service #A; R t2 is an example of the second threshold, which is used to indicate the sensing range of the sensing entity #2 for the service demand of the sensing service #A; R t3 This is an example of the third threshold, which is used to indicate the perception range of the service demand of the perception entity #3 for the perception service #A.

[0365] It should be understood that the above R t1 , R t2 , R t3 It is determined by SSCF based on the business needs of perception service #A, that is, when the perception target moves out of the perception range of the business needs of perception service #A corresponding to the current perception entity, business continuity may be affected. At this time, the perception data of the current perception entity may be invalid. In this case, it can be determined that another perception entity will continue to execute the perception service #A.

[0366] It can be understood that the maximum perception range of the perception entity is larger than the perception range for ensuring the continuity of the perception business. The perception target moves out of the perception range for ensuring the continuity of the perception business, but is still within the maximum perception range of the perception entity. At this time, due to the distance problem of the perception target, the continuity of the perception business may not be guaranteed, and the perception data of the perception entity may also be invalid.

[0367] Among them, configuration information #3 can also include determination mode #3, and determination mode #3 is used to instruct SSCF to determine another perception entity to perform perception service #A.

[0368] S820, perception entity #1, perception entity #2 and perception entity #3 send response message #3 to SSCF.

[0371] SSCF can activate perception entity #1 to perform perception service #A. For example, SSCF can determine that perception entity #1 can be activated to perform perception service #A based on the business requirements of perception service #A and the location information of the current perception target.

[0372] Sensing entity #1 executes sensing service #A and sends sensing data to SDPF.

[0373] The sensing entity #1 determines based on the sensing data that the distance R1 between the current sensing target position and the sensing entity #1 position is greater than or equal to R t1 .

[0374] An optional understanding is that perception entity #1 can determine that the current position of the perception target has moved out of or is about to move out of the perception range that ensures the business continuity of the perception service. In this case, it can request the control network element to determine another perception entity to execute perception service #A to ensure the continuity of the perception service #A.

[0375] S840, perception entity #1 sends request information #3 to SSCF.

[0376] Perceived entity #1 based on R1 being greater than or equal to R t1 A request message #3 is sent to the SSCF, where the request message #3 is used to request the SSCF to determine another perception entity to perform perception service #A.

[0377] Among them, the request information #3 may include the identifier of the perception service #A, the identifier of the perception entity #1, the location information of the perception target, etc.

[0378] S850, SSCF determines the second perception entity according to request information #3.

[0379] Exemplarily, SSCF may determine, based on an algorithm, perception entity #2 to perform perception service #A.

[0380] SSCF may also determine perception entity #2 in other ways, which is not limited in this embodiment of the present application.

[0381] It should be noted that the SSCF can obtain indication information, perception capability information and location information of the perception entity #1 and adjacent perception entities during the registration phase.

[0382] Among them, the indication information of the perception entity can be the identifier or name of the perception entity, or it can be other information indicating the perception entity, which is not limited in the embodiments of the present application.

[0384] SSCF may determine perception entity #2 to perform perception service #A based on indication information, perception capability information, and location information of perception entity #1 and adjacent perception entities.

[0385] S860, SSCF sends request information #4 to perception entity #2.

[0386] Request information #4 is used to request the perception entity #2 to execute the perception service #A.

[0387] Among them, the request information #4 may include the service identifier of the perception service #A, the identifier of the perception entity #1, the identifier of the perception entity #2, the perception information, etc.

[0388] S870, perception entity #2 executes perception service #1.

[0389] The sensing entity #2 performs the sensing service #A based on the request information #4.

[0390] S880, the sensing entity #2 determines that R2 is less than or equal to R according to the configuration information #3. t2 .

[0391] Sensing entity #2 uploads the sensing data to SDPF.

[0392] Based on the perception data, the perception entity #2 determines that the distance between the current perception target position and the perception entity #2 position is R2. When R2 is less than or equal to R t2 , perception entity #2 determines that perception entity #1 can stop executing perception service #A.

[0393] When executing perception service #A, perception entity #2 can determine that the perception target has entered the perception range that ensures the service continuity of the perception service, and thus can instruct perception entity #1 to stop perception, or can instruct perception entity #1 to stop perception through SSCF.

[0394] Instructing perception entity #1 to stop perception through SSCF may specifically include the following steps S890a and S891a; and perception entity #2 instructing perception entity #1 to stop perception may specifically include the following step S891b.

[0395] S890a, perception entity #2 sends request information #5 to SSCF.

[0396] Among them, request information #5 is used to instruct perception entity #1 to stop executing perception service #A.

[0397] In a possible implementation, perception entity #2 may send a perception response message to SSCF, and SSCF instructs perception entity #1 to stop executing perception service #A according to the response message.

[0398] Among them, the request information #5 may include the identifier of the perception service #A.

[0399] S891a, SSCF sends request information #6 to perception entity #1.

[0400] Among them, request information #6 is used to instruct perception entity #1 to stop executing perception service #A.

[0402] The request information #6 may include the identifier of the perception service #A.

[0403] S891b, perception entity #2 sends request information #6 to perception entity #1.

[0404] Perceiving entity #2 can be based on R2 being less than or equal to R t2 The result determines that the sensing target has entered the sensing range of sensing entity #2 that ensures the continuity of sensing service, and instructs sensing entity #1 to stop sensing.

[0405] In a possible implementation, the sensing entity #2 may send a sensing response message to the sensing entity #1, and the sensing entity #1 stops executing the sensing service #A according to the response message.

[0406] S892, perception entity #1 stops executing perception service #1 according to request information #6.

[0407] Before receiving request information #2, perception entity #1 can execute perception service #A simultaneously with perception entity #2. When the perception target has entered the perception range where perception entity #2 can ensure the business continuity of the perception service, perception entity #1 stops executing perception service #A.

[0408] Based on the above technical solution, perception entity #1 can request SSCF to determine another perception entity to continue to perform the perception service based on the configured perception range that ensures the continuity of the perception service. When the perception target enters the perception range where another perception entity can ensure the business continuity of the perception service, perception entity #1 stops perceiving, thereby ensuring the continuous upload of effective perception data of the perception service, meeting the needs of the perception service, and improving the perception capability.
